Office Action

§DP
DETAILED ACTION 1. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . 2. Applicant's preliminary amendment filed on 02/21/2024 is acknowledged. Claims 25-50 are pending. 3. The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP §§ 706.02(l)(1) - 706.02(l)(3) for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/process/file/efs/guidance/eTD-info-I.jsp. 4. Claims 25-50 are rejected on the ground of nonstatutory double patenting as being unpatentable over the claims of U.S. Patents No. 10465007 (IDS), 11560430 (IDS), and 12258407. Although the claims at issue are not identical, they are not patentably distinct from each other because the instant claims are anticipated the claims of each of the cited patents. Instant claims recite anti-PD-1 antibodies defined by their amino acid sequences, and are directed to nucleic acids and vectors encoding the antibodies (claims 25-41), to host cells comprising the nucleic acids and methods of producing the antibodies (claims 42-46), and to a composition comprising antibodies (claims 47-50). Each of the cited U.S. patents recites the same anti-PD-1 antibodies, as defined by their amino acid sequences (see SCORE). Specifically, US ‘007 claims are directed to the same anti-PD-1 antibodies (claims 1-9), composition comprising the antibodies (claim 10), and a host cell comprising polynucleotides encoding the antibodies (claim 11). All claims of each of US ‘430 and US ‘407 are directed to methods of treatment utilizing the same anti-PD-1 antibodies. Since the antibodies are recombinantly produced, nucleic acids encoding the antibodies, vectors, host cells and methods of producing the antibodies are inherent in teaching of the antibodies. 5. Conclusion: no claim is allowed. 6. Any inquiry concerning this communication or earlier communications from the examiner should be directed to ILIA I OUSPENSKI whose telephone number is (571)272-2920.
